guttation การใช้

• Plants can get rid of excess water by transpiration and guttation.
• Removing dew and guttation fluids from the canopy can help lessen disease severity.
• The question of whether liquid emitted by plants via guttation, which bees ingest, posed an additional risk was unanswered.
• At night in some plants, root pressure causes guttation or exudation of drops of xylem sap from the tips or edges of leaves.
• It was found that when bees consume guttation drops collected from plants grown from neonicotinoid-coated seeds, they die within a few minutes.
• They are taken up by a plant s vascular system and expressed through pollen, nectar and guttation droplets from which bees forage and drink.
• Girolami et al . ( 2005 ) found that guttation drops from corn plants germinated from neonicotinoid-coated seeds could contain amounts of insecticide consistently higher than 10 mg / l, and up to 200 mg / l for the neonicotinoid imidacloprid.
